The renal artery is the branch of the abdominal aorta given off at the level of second lumbar vertebra. The present case, reports presence of multiple renal arteries on both sides.
We report a case of an 18 yr old female, having five renal arteries, three on the right side and two on the left side found on the CT Aniographic image analysis. All of them originated opposite to the body of the L1 vertebra from the aorta in close approximation and entered the substance of the kidney through the hilum.
Commonly reported variation regarding renal arterial vasculature is presence of an accessory renal artery along with the main renal artery. But the number of total renal arteries more than three or four is less frequently reported. Embryologically the accessory renal arteries represent the persistence of foetal arteries supplying the developing kidneys.
Presence of multiple renal arteries is of profound clinical importance because of increasing number of surgical and radiological intervention in the renal hilar area. Moreover there is gradual preference towards the minimally invasive surgeries. So knowledge of these variations should be kept in mind prior to intervention in this area.
